Benign gastric schwannoma: how long should we follow up to monitor the recurrence? A case report and comprehensive review of literature of 137 cases.

We aimed to explore the optimal follow-up time for benign gastric Schwannoma. Benign gastric Schwannoma is an uncommon type of gastric neoplasias. Most of the studies are case reports and case series. Although it is generally considered to be benign, the optimal follow-up time and the chance of recurrence have not yet been investigated fully. We presented a case of benign gastric Schwannoma and systematically reviewed published case series with follow-up data. Eight studies were included, totaling 137 patients (44 male and 93 female) with the median follow-up time ranging from 22-132 months across different studies. No recurrence had been recorded during the follow-up period. Benign gastric Schwannoma rarely recurs after complete surgical resection. Long-term survival will be expected in most patients.
